A London flight to Philadelphia has been diverted to Dublin after reports of a “chemical spillage” on board.
American Airlines said two crew members and one passenger went to hospital “for evaluation” after flight AA729 from Heathrow landed at 13:15 GMT on Monday.
Airbus A330-300 landed due to an odour “caused by a spilled cleaning solution in the galley”, it added.
One passenger wrote on Twitter that the spillage “led to sickness outbreak and an emergency landing”.
Another passenger wrote that he and dozens of others had been left “standing around” Dublin Airport.
A spokeswoman for Dublin airport said the flight was diverted “for a medical emergency”.
“As per standard operating procedures there was a full turn-out of Dublin Airport’s emergency fire services,” she added.
A second American Airlines flight was met by emergency vehicles after it also was diverted to Dublin on Monday.
The airline said flight 787, from Paris to Charlotte in North Carolina was diverted after a passenger fell ill.
The passenger was taken from the plane for treatment and the flight is scheduled to depart later on Monday, a spokeswoman added.
